MACHINERY FOB OILING- THE JOURNALS OF LOCOMOTIVES.

Specification of Letters Patent No. 22,586, dated January 11, 1859.

To all whom it may concern:

Be it known that I, STEPHEN Soo'r'roN, of Richmond, in the county of Wayne and State of Indiana, have invented a new and Improved Mode of Oiling Locomotive Machinery; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accom panying drawings and to the letters of reference marked thereon.

The nature of my invention consists of a metal box, through which passes an upright shaft, the lower end of which goes down through the bottom of said box and has on it a piece of leather or other ma terial made to fit tight against the bottom side of said box to prevent the escape of oil through the aperture around said shaft when it is at rest. The upper end of said upright shaft passes up through a hole in a portion of the upper end of said oil box and on the upper end of this shaft is a nut which can be raised or lowered to increase or diminish the amount of play up and down of the upright shaft, thereby regulating the amount of oil that is allowed to escape at the bottom. The said upright shaft has on a portion of its length an enlargement for a weight, between which and the bottom of the box is a spiral spring which allows the shaft to play up and down when actuated by the jolting of a vehicle and by that means causes a portion of oil to escape, the amount of which can be accurately gaged by two devices hereafter to be described.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

The box C can be of any shape or size that may be desired, with a hole in the top large enough to admit the weighted portion A of upright shaft B.

D is a hole drilled through the bottom of box C, to allow the shaft B to pass through and also to let the oil escape. On the lower end of shaft B is a nut of leather or other material, made to fit tight like a cork when pressed upward against the outlet D.

F is a spiral spring inserted under the weight A, and of sufficient power to keep the nut E tight up against D when the machinery is at rest.

J, is a nut working on a thread for the purpose of taking up the play of shaft B up and down and thereby regulating the amount of oil that escapes at D.

H is a metal cup with the open and upward and a screw thread on the outside corresponding with one on the inside of the neck T or hole in the top of box G into which H is screwed and by raising or lowering H another mode is provided for regulating the extent of up and down motion of upright shaft B, and consequently the escape of oil at D.

K is a simple cap, with or without a screw thread for keeping out dirt.

S is a hole drilled through the bottom of H for the passage of upright shaft B.

I is a hole for filling box G by pouring oil into cup H.

R is intended to represent the upper timber of a. truck for cars, on which the box C is placed. r

G is a tube to convey the oil that escapes from D down to the journal and where box C is placed over aspring the additional tube L is used into which Gr enters and they play together at their junction in order to compensate for the motion of the spring. This tube empties on the top of the brass boxing, through which holes are drilled dolwn to the journal 0 for the passage of 01 There this invention is applied to iron trucks the box C is placed immediately on the journal box on the tube G passes down to the brass boxing P.

This invention is applicable in different forms to all the journal boxes now in use on railroads.

Operation: The box C being properly adjusted upon a truck and the train started a constant jolting is produced, which causes the weighted shaft B to play up and down, every downward motion of which allows a port-ion of oil to escape at D. When the train stops the spring F lifts up the pertheir equivalents for the purposes herein specified.

3. I claim the nut J, when combined with upright shaft B and cup H, or their equiv- 15 alents in the manner and for the purposes herein specified.

STEPHEN SCOTTON.
